Top 10 Greatest Moments of Undertale

The Top Ten

1 Saving everyone in the final battle against Asriel, including Asriel himself

I'm going to be honest, during this part of the battle, I cried. to be honest I was crying tears throughout the whole battle, but I cried especially during this part. And not tears of sadness, either. Tears of pure, utter joy. It was a really weird but beautiful feeling.

I think don't give up and Undyne the undying a little greatest but I think this is good too.

The ending was beautiful. Just beautiful. - Delgia2k

It was so sad! It made me cry, but I loved it. Flowey may not be that amazing, but Asriel sure is. - unipuff123

2 Sans' boss fight

I've got a better question for ya. Do you want to have a bad time? -Sans

Sans is the obvious choice, because of his major role in every Pacifist/Genocide route you take. In a Pacifist run, he is a smartass and comically retorts to his brother's antics, and in a Genocide run he is a total badass and dunks you like you know you deserve.

I did the whole geno run for that SONG.

Go ahead, try to hit me it you're able

3 Mettaton transforms into Mettaton EX

Is it weird for a 13 year old girl to find him hot

I don't know why that was so beautiful, but it kinda was

Oh yes he is so wonderful as mettaton ex! #greatestmoment

I screamed so hard,it was amazing

4 Sans' opening monologue to his boss fight

There can't have been a more epic quote in the genocide run, but yeah I agree it's overrated.

every undertale fan will remember this

yup - ketchupboysans

Best song

5 Um Jammer Alphys (parody of UmJammer Lammy)

Saying that Alphys was hilarious in this
is honestly quite the understatement - xandermartin98

6 The Giantess Toriel X Asriel scene from Alphys VS Undyne


7 One-hit KO on Sans

Too true to be real.

8 0.0000001 HP

Why is there fetish cringe above this?

This is my second favorite purely because how amazing it is ^_^ - unipuff123

9 Naming your character John Cena

Greetings. I am John Cena.


You can't due to 6char limit.

Closest you'll get is JCena. - SoaPuffball


10 Alphys' deepest, darkest secret

The Contenders

11 Toriel baking you a pie in the Pacifist ending


You finally got your pie!

I baked you a pie.
oH bOy WhAt FlAvOr?

I baked you a pie. Oh boy what flaver. Pie flaver

12 Cooking with Undyne

This is by far my favorite moment (not including boss fights) in the game. I was literally dying of laughter throughout this scene!

This is honestly one of my favorite moments, from the heart-touching dialogue to pulverizing the ingredients.

This is easily the funniest part in the game. I love this scene so much! It needs to be higher.

*Papyrus jumps out the window the cooking burned the house down

13 Papyrus tracking footprints through the correct path of his own invisible maze

Papyrus is so funny. I'm just looking through this list for a papyrus moment

It shows Papy's kindness, a lovely trait to have, but it can always lead to a weakness.


14 Burgerpants' facial expressions

Haha, the faces he makes are scary

How is this not higher?!

Wake me up - Dreamsthefox


15 "But nobody came."

These words are the very words you see and hear when you know your going down the beaten path

It amazing how three words can be so ominous and foreboding. Really sends a chill down your spine.

But nobody came.

16 Sans pretending to spare you

This is the best moment of all

Get dunked on

Get dunked on

Then WAM! You did it.

17 Flowey transforms into Omega Flowey

That moment when you realise this game can just push wow factor a little bit further

Epic epic, and that song (both finale and your best nightmare) are epic.

YES. Omega Flowey is epic. Vote if you agree.


Lol I liked this part

18 Listening to all of Napstablook's song tapes even though practically all of them are literally the exact same five-second song loop
19 Stretching Lesser Dog's neck until it goes all the way up and down the screen

* Lesser dog has gone where no dog has gone before.

Lesser dog is... I don't even know

That was SO cute! - Pegasister12

This should be number 1! This makes me laugh every time!
*Lesser dog is unpettable but appreciates the attempt - meppifier

20 Asgore shatters the Mercy button into pieces

"Human... It was nice to meet you. Goodbye." - SPMZDE

Too cool!... and kinda scary

21 Undyne the Undying Undyne is a main character in Toby Fox's 2016 RPG, Undertale. She is the heroic fishlike captain of the Royal Guard, who takes it upon herself to protect the monsters of the Underground. Her name is derived from the word "Undine", and is a pun on the word "Undying". Her most loved monsters are her mentor, more.

This should’ve been number one. Not only is it a heroic speech with music almost as good as the track that follows, but it shows how determined undyne really is. P.S. undyne is harder than sans. I pulled my hair out during every attack each attempt, while I can do the sans opening with my eyes closed.

22 That one question in Mettaton's quiz: "Who does Dr. Alphys have a crush on?"

Hgyvghwsd undyne got it correct yey

23 The revelation of what EXP and LOVE actually stand for
24 Mettaton crossdressing and singing a love song

I was laughing so hard that I was crying!

I couldn't stop grinning like an idiot during this part, Mettaton is just too funny sometimes. And he... kinda looked good in the dress

25 Temmie's Facial Expressions
26 Using the Instant Noodles During Battle On a Pacifist Run

Five minutes.

Just cause its hilarous - lucario_ninetales

27 Everyman getting his head eaten by butterflies

Oh. Right.

28 Being forced to literally flee from Undyne in order to spare her
29 True Pacifist Ending

It was so amazing

30 Sans literally counting the number of times he's killed you in his boss fight

This pisses me off...

Asgores easy I only died 5 times

I thought that was Asgore? I don't know because I'm stuck on Asgore - NoOreoForU

31 Finding traces of W.D. Gaster
32 Burgerpants being used as Dean in The Iron Mettagiant
33 Naming your character Hitler in the Genocide Run

Greetings. I am Hitler.

34 The Giantess Alphys scene from Alphys VS Undyne

Okay, this was just flipping hilarious.

Easily the most amazingly fetishistic scene I've ever read in fanfiction, and also one of the funniest to boot.

The part where Undyne snuck inside Alphys' brain and made her dance naked to the Mew Mew Kissy Cutie theme song while being publicly filmed on live television was just priceless. - xandermartin98

35 The pacifist ending credits

This made me cry. 11 minutes of pure joy. Just seeing the characters so happy on the surface, it's so heartwarming. - Bramblestar


36 Your Soul Reforming Itself Back Together from Sheer Determination During the Battle Against Asriel


37 Sans' Whoopie-Cushion-In-The-Hand Prank
38 Mad Dummy's boss fight


39 Papyrus' boss fight

I got teary-eyed when he died, no shame admitting it.

40 Muffet's boss fight

Anybody else notice that Muffet's boss fight is 59 in this list and Spider Dance is number 59 on the soundtrack.

41 Asriel destroys the Barrier
42 The bird that carries you over a disproportionately small gap
43 Alphys ranting obsessively about anime
44 "There's a Mettaton-shaped hole in my Mettaton-shaped heart!"

Mettaton! don't leave! Your show made us so happy!

45 The extremely long motivational (and expositional) speech in Asgore's castle

Made me cry hard the first time playing

46 Talking to everyone during the pre-ending stage of the True Pacifist Run after the final boss
47 Papyrus jumping through a window

Sans's quotes would have been the best, but Papyrus out-spaghettis them all...

I cracked up at that part. Papyrus is so funny and weird

Whoopsy Doopsy! I just remembered! I have to go to the bathroom! You two have fun! BYE! *Papyrus jumps out the window*

48 Sans informing you that he literally would have murdered you in cold blood, had Toriel not told him not to
49 "Smells like Mettaton."

Smells like a Luigi. - SanicHeghog123


"Smells like bones." - Papyrus
"Smells like bad puns." - Sans

Smells like sushi -Undyne

50 "That's the trash can. Feel free to visit it any time."

Oh Papyrus...
